"Don't forget body moisturiser," Dr. Nussbaum said. "Dry skin equals dull skin. Kiehl's Since 1851 Creme de Corps ($18) is a great silky, nongreasy lotion that absorbs easily into the skin. It contains a blend of hydrating ingredients like cocoa butter and sesame oil to soften skin, while the plant-derived squalane helps to restore the skin's natural moisture balance."
